I see a lot of issues relating to the rear clutch in the A727. I.E. catastrophic burn-up. While reassembling, I found a lot of slop (over .080) between the piston and the Bellevue spring. I ordered a slightly taller piston from a source recommended by responders in a previous post. Upon...
Thanks for the pics. I'll do some more research. Just my luck to drill it in the wrong place. It looks like it's where the inner race bears on the case.
I have seen videos of trans builders indicating that the small oil passages can be opened up a bit to allow for better oil flow. Specifically, the passages for the sun gear bushings and the planetary gears. Will a minor change in these cause a reduced pressure in other needed areas? Could flow...
I've read all of the posts so far. This story reminds me of an eye opening experience I had one summer back in the mid seventies while working at a local job shop. The foreman handed me a PTO drive shaft and said, "Make another one just like this one." So I did. Two days later, the customer...
Thank you, Doug. Just enough to assure myself that there was no "varnish" on the sliding surfaces, except for that one sticky throttle valve. You're right. 1500 does not remove material. I knew I removed some material on the throttle valve, but I was not able to measure it with a ten thousanths...
440, I forgot to mention to take lots of pictures. I did the spool valves ok, but didn't do enough detail on the servos and accumulator. Then I find out that there have been many changes to those parts. The service manuals I have do not really go into enough detail on what parts go where. I'm...
Dave, thank you for the encouragement. I can't afford a valve body anyway. I did the polish treatment to assure myself that there was no "varnish" on the valve surfaces. I was also worried that the very sharp edges of the valves would nick the edges of the aluminum holes as they were inserted...
440, '71 was a major transition year as the history story goes. This rebuild is my first auto trans job. If I get through it, I'll be able to put a big check mark on my bucket list. According to codes, my trans is a '70. However, I believe there are '71-on parts in it. The trans that was in it...
What do you want to do? Contact the owner? Buy it back? what. You could try contacting the registrar of motor vehicles in MN. (DMV). I don't know if they'll give you that information. You may have already tried. If you have a close relationship with a member of law enforcement, you might be able...
L 71, I knew that was a possibility. I decided to take the chance. I'll get it all back together and get back to you on the "ruined" issue. What symptoms would I be looking for other than not working?
Gentlemen, experts too, This forum is the best I can do for my early 70's motorhome. It has the info I need for the Dodge running gear. The trans had fried and melted the clutches in the rear clutch pack. I have seen many causes for this condition in the forum here, the manual, and in other net...
Thanks for the contribution. I know that's good advice for some, but I'm a shade tree type. I really don't do cars much. I do lathes and mills. You know, like, I'd rather shoe the horse than ride it. My show pieces are out working somewhere. My first time in a 727. What a fascinating piece of...
I'd get the spare 727, but I'm trying to downsize. I have a lakeshore lot up north. Thus the need for a functioning MH. OBTW I have a 318, mid seventies vintage. reworked heads for unleaded, mildly ported, about 30M. 2 BBL. with manual four speed. AND a late 50's 354 hemi, disassembled with...
Thanks for the info on how the whole thing works, and the chart. It gives me greater insight into what and where to look. Right now, I'm focused on the pump. There is no polish on any of the surfaces. I'd say it must have sucked up some sand at some time in it's past. I can machine the stator...
